At a council meeting of the N.P.A. on February 25^th it was decided to hold a test match confined to the 10 Tractor Competitors who secured the highest marks in Mullingar. This council did not believe that Mullingar provided a fair test on account of the roughness of the match field.
The test match was held in Milltown, Co. Kildare on March 18^th and each competitor was obliged to rise Middle and Furrow and plough 1,850 sq. yards in three hours. This was to be ploughed in two plots, one in the forenoon and one in the afternoon. The competitor with the highest combined marks was deemed the winner.

As the fifties wore on, two aspects combined to suggest the passing of an era. One was J.J. Bergin's advancing years, the other was the acceleration into tractor mechanisation and the ever increasing abandonment of the horse.
In 1958 it was already clear that The Old Lion (Bergin) was fading. His poor health the previous year had prevented him from taking his usual part in the affairs of the Association. His condition gradually failed and on March 13^th, 1958, J.J. Bergin, founder of the National Ploughing Association, died at Maybrook, Athy, Co. Kildare.

The 1965 Championships also saw the arrival of ESSO on the scene. ESSO offered to replace The Supreme Trophy initially presented by Vigzol Lubricants in 1946 and also to provide sponsorship for the Event.
